dnbd3.git/src/server, branch v2.1Distributed Network Block Device 3 --rewrite for Kernel 3.xhttps://git.openslx.org/dnbd3.git/atom/src/server?h=v2.12016-02-01T11:41:11+00:00[SERVER] BREAKING: Get rid of pseudo case-insensitivity2016-02-01T11:41:11+00:00Simon Rettberg2016-02-01T11:41:11+00:00urn:sha1:81c9da3c9d55fab13ab9a912cade320015d01613
This was a wrong decision made long time ago, and it's broken in
certain scenarios (eg. two servers serving from same NFS mount).
Also it's of limited use anyways since it only supportes ASCII and
would ignore umlauts, so blöd and BLÖD would still be considered
two different images.
So if you relied on this "feature" in any way, be careful when
updating.
[SERVER] Fix a lot of (mostly harmless) data races2016-01-11T11:09:23+00:00Simon Rettberg2016-01-11T11:09:23+00:00urn:sha1:d9c2a6cf943ca08f31f61a3fada940f77e3a03d3[SERVER] Performance: Optimized some functions (gprof)2015-12-17T14:58:06+00:00Simon Rettberg2015-12-17T14:58:06+00:00urn:sha1:1460b746b6f5482ce1c56a30af232e824e316e56
A run with gprof revealed that background replication is a huge CPU hog.
The block selection was very slow and has been improved a lot.
Minor improvements were made to other functions that scan the cache map
of an image and are thus relatively slow.
[SERVER] image_markComplete now handles locking so we remove() unlocked2015-12-17T13:20:12+00:00Simon Rettberg2015-12-17T13:20:12+00:00urn:sha1:3de54fac10b3dbdcfc3573e175078c7104837ef3[SERVER] Cancel scanning of image dir if _shutdown is set2015-12-16T17:20:55+00:00Simon Rettberg2015-12-16T17:20:55+00:00urn:sha1:2bc1381256c860b6deb3044d3263cea625118793
So you can cancel image loading on startup via Ctrl-C
[SERVER] Fix image_calcBlockCrc32: Use 64bit for fileSize param2015-12-16T17:09:04+00:00Simon Rettberg2015-12-16T17:09:04+00:00urn:sha1:b5851655ab5f1cff84221e69fb6a74326b80bc22
Using uint32_t for fileSize is not too clever :(
[SERVER] More fine grained locking for RPC; better error logging2015-12-16T16:28:52+00:00Simon Rettberg2015-12-16T16:28:52+00:00urn:sha1:f49b63e11de50e72f85f8c6688da36d89bf17b87[SERVER] Update config example2015-12-15T17:05:46+00:00Simon Rettberg2015-12-15T17:05:46+00:00urn:sha1:b4cf06abaa5278b016c2036b6574d1be129f3d99[SERVER] Remove non-working images from list, plus refactoring2015-12-15T16:45:44+00:00Simon Rettberg2015-12-15T16:45:44+00:00urn:sha1:72104f2e83fa724f9667c876dca17a2c5ee9b2a2
Now that we can automatically load unknown images from disk on request,
it makes sense to remove non-working images from the image list. On
future requests, we will look for them on disk again, which is nice
in case of temporary storage hickups.
Also, some more ore less related locking has been refined (loading images,
replicating images)
